If you need to move a bench around a public garden, plan for a typical weight of about 80 to 200 pounds, or roughly 36 to 91 kilograms. The exact number depends on the material. Wooden slat benches are usually on the lighter end at 70 to 120 lbs, while powder-coated steel and recycled plastic benches often fall between 100 and 180 lbs. Decorative cast iron or concrete benches are much heavier and can weigh 250 to 400 lbs or more, so they usually require equipment and extra hands.
Before moving anything, check whether the bench is bolted down. Many public garden benches are secured to concrete pads, pavers, or buried anchors for safety. If so, unbolt it first and store the fasteners in a labeled bag. For a bench over about 80 lbs, use at least two people or a hand truck. A furniture dolly, heavy-duty cart, or even a plywood sled can help you cross grass, gravel, or wet ground without tearing up the garden. If the bench has removable slats or armrests, take them off to reduce weight and make the bench easier to grip.
Lift with your legs, keep the bench close to your waist, and avoid twisting while carrying. Plan your route before you lift, and set the bench down on level ground. If the bench is heavier than you can comfortably control, do not force it. Rent a utility cart or ask grounds staff for help. In public garden settings, it is also a good idea to get approval from the garden manager before moving benches, especially if paths are narrow, plantings are close, or the ground is soft after rain.
